json - How do I make raw unicode encoded content readable?

Question

I used net/http request a web API and the server returned a JSON response. When I print the response body, it displayed as raw ASCII content. I tried using bufio.ScanRunes to parse the content but failed.

I also tried write a simple server and return a unicode string and it worked well.

Here is the core code:

func (c ClientInfo) Request(method string, url string, form url.Values) string {
    req, _ := http.NewRequest(method, url, strings.NewReader(c.Encode(form)))
    req.Header = c.Header
    req.AddCookie(&c.Cookie)
    resp, err := http.DefaultClient.Do(req)
    defer resp.Body.Close()
    if err != nil {
        fmt.Println(err)
    }

    scanner := bufio.NewScanner(resp.Body)
    scanner.Split(bufio.ScanRunes)

    var buf bytes.Buffer
    for scanner.Scan() {
        buf.WriteString(scanner.Text())
    }
    rv := buf.String()
    fmt.Println(rv)
    return rv
}

Here is the example output:
